Change From Baseline in NeuroCart test battery Score
Time Frame: Screening, Day 1, Day 8

Change from Baseline in Bond & Lader Visual Analogue Scale (VAS)
Time Frame: Day 1, Day 8
|
Visual Analogue Scale (VAS) is made up of 16 pairs of alternative descriptors of mood and attention at either end.
The Bond-Lader of a 10 cm line.
Participants will rate their feelings at the time of assessment by indicating the point on the line which best represent their mood.
Each item is scored by measuring the position relative to the left hand end of the line and levels of anxiety, sedation, and dysphoria are then calculated from the combined scores of selected items.
The score ranges from 0 to 100, with a high score reflecting a high level of anxiety, sedation or dysphoria.
